II. Preparing Carrageenan

Carrageenan is available from chemical supply companies (e.g., Sigma). Here, we describe how to prepare carrageenan solutions of various concentrations and pH. You will need:

Once you have the desired pH, add food coloring to the HCl solution. This will provide contrast between the HCl solution and the carrageenan when performing the Hele-Shaw experiment.
